Pin AssignmentFigure 1.Pin Configuration1. DescriptionThe Atmel ®AT88SC0808C member of the Atmel CryptoMemory ®family is a high-performance secure memory providing 8-Kbits of user memory with advanced security and cryptographic features built in. The user memory is divided into eight 128-byte zones, each of which may be individually set with different security access rights or effectively combined together to provide space for one to eight data files.1.1 Smart Card ApplicationsThe AT88SC0808C provides high security, low cost, and ease of implementation without the need for a microprocessor operating system. The embedded cryptographic engine provides for dynamic and symmetric mutual authentication between the device and host, as well as performing stream encryption for all data and passwords exchanged between the device and host. Up to four unique key sets may be used for these operations. The AT88SC0808C offers the ability to communicate with virtually any smart card reader using the asynchronous T = 0 protocol (Gemplus Patent) defined in ISO 7816-3.1.2 Embedded ApplicationsThrough dynamic and symmetric mutual authentication, data encryption, and the use of encrypted checksums, theAT88SC0808C provides a secure place for storage of sensitive information within a system. With its tamper detection circuits, this information remains safe even under attack. A 2-wire serial interface running at 1.0MHz is used for fast and efficientcommunications with up to 15 devices that may be individually addressed. The AT88SC0808C is available in industry standard 8-lead packages with the same familiar pinout as 2-wire Serial EEPROMs.V CC =C1RST=C2SCL/CLK=C3NC=C4ISO Smart Card ModuleC5=GND C6=NC C7=SDA/IO C8=NCNC NC NC GND123487658-lead SOIC, PDIP V CC NC SCL SDAV CC =C1NC=C2SCL/CLK=C3NC=C4TWI Smart Card ModuleC5=GND C6=NC C7=SDA/IO C8=NCAT88SC0808C [SUMMARY DATASHEET]Atmel-2024MS-CryptoMem-AT88SC0808C-Datasheet-Summary_1220133Figure 1-1. Block Diagram2.Pin Descriptions2.1Supply Voltage (V CC )The V CC input is a 2.7V to 5.5V positive voltage supplied by the host.2.2 Clock (SCL/CLK)In the asynchronous T = 0 protocol, the SCL/CLK input is used to provide the device with a carrier frequency f . The nominal length of one bit emitted on I/O is defined as an “elementary time unit” (ETU) and is equal to 372/f. When the synchronous protocol is used, the SCL/CLK input is used to positive edge clock data into the device and negative edge clock data out of the device.2.3 Reset (RST)The AT88SC0808C provides an ISO 7816-3 compliant asynchronous answer to reset sequence. When the reset sequence is activated, the device will output the data programmed into the 64-bit answer-to-reset register. An internal pull-up on the RST input pad allows the device to be used in synchronous mode without bonding RST. The AT88SC0808C does not support the synchronous answer-to-reset sequence2.4 Serial Data (SDA/IO)The SDA pin is bidirectional for serial data transfer. This pin is open-drain driven and may be wired with any number of other open drain or open collector devices. An external pull-up resistor should be connected between SDA and V CC . The value of this resistor and the system capacitance loading the SDA bus will determine the rise time of SDA. This rise time will determine the maximum frequency during read operations. Low value pull-up resistors will allow higher frequency operations while drawing higher average power. SDA/IO information applies to both asynchronous and synchronous protocols.When the synchronous protocol is used, the SCL/CLK input is used to positive edge clock data into the device and negative edge clock data out of the device.V CCAT88SC0808C [SUMMARY DATASHEET]Atmel-2024MS-CryptoMem-AT88SC0808C-Datasheet-Summary_12201343.*NOTICE: Stresses beyond those listed under “AbsoluteMaximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other condition beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect device reliability.Table 3-1.DC CharacteristicsNote:1. V IL min and V IH max are reference only and are not tested2. To prevent latch up conditions from occurring during power up of the AT88SCxxxxC, V CC must be turned onbefore applying V IH .

Device Operation for Synchronous ProtocolsClock and Data Transitions:The SDA pin is normally pulled high with an external device. Data on the SDA pin may change only during SCL low time periods (see Figure 4-3 on page 7). Data changes during SCL high periods will indicate a start or stop condition as defined below.Start Condition:A high-to-low transition of SDA with SCL high is a start condition which must precede any other command (see Figure 4-4 on page 7).Stop Condition:A low-to-high transition of SDA with SCL high is a stop condition. After a read sequence, the stop command will place the EEPROM in a standby power mode (see Figure 4-4 on page 7).Acknowledge:All addresses and data words are serially transmitted to and from the EEPROM in 8-bit words. The EEPROM sends a zero to acknowledge that it has received each word. This happens during the ninth clock cycle (see Figure 4-5 on page 7). Memory Reset:After an interruption in protocol, power loss or system reset, any 2-wire part can be reset by following these steps: 1. Clock up to nine cycles2. Look for SDA high in each cycle while SCL is high3. Create a start conditionAT88SC0808C [SUMMARY DATASHEET] Atmel-2024MS-CryptoMem-AT88SC0808C-Datasheet-Summary_1220136 Figure 4-1.

Multiple zones allow for different types of data or files to be stored in different zones. Access to the user zones is allowed only after security requirements have been met. These security requirements are defined by the user during the personalization of the device in the configuration memory. If the same security requirements are selected for multiple zones, then these zones may effectively be accessed as one larger zone.6. Control LogicAccess to the user zones occurs only through the control logic built into the device. This logic is configurable through access registers, key registers and keys programmed into the configuration memory during device personalization. Also implemented in the control logic is a cryptographic engine for performing the various higher-level security functions of the device.AT88SC0808C [SUMMARY DATASHEET]Atmel-2024MS-CryptoMem-AT88SC0808C-Datasheet-Summary_12201397. Configuration MemoryThe configuration memory consists of 2048 bits of EEPROM memory used for storing passwords, keys and codes and defining security levels to be used for each user zone. Access rights to the configuration memory are defined in the control logic and may not be altered by the user.AT88SC0808C [SUMMARY DATASHEET]Atmel-2024MS-CryptoMem-AT88SC0808C-Datasheet-Summary_122013108. Security FusesThere are three fuses on the device that must be blown during the device personalization process. Each fuse locks certain portions of the configuration memory as OTP memory. Fuses are designed for the module manufacturer, card manufacturer and card issuer and should be blown in sequence, although all programming of the device and blowing of the fuses may be performed at one final step.9. Protocol selectionThe AT88SC0808C supports two different communication protocols.• Smart Card Applications:The asynchronous T = 0 protocol defined by ISO 7816-3 is used for compatibility with the industry’s standard smart card readers• Embedded Applications:A 2-wire serial interface is used for fast and efficient communication with logic or controllersThe power-up sequence determines which of the two communication protocols will be used.9.1 Asynchronous T = 0 ProtocolThis power-up sequence complies with ISO 7816-3 for a cold reset in smart card applications.• V CC goes high; RST, I/O-SDA and CLK-SCL are low • Set I/O-SDA in receive mode • Provide a clock signal to CLK-SCL •RST goes high after 400 clock cyclesThe device will respond with a 64-bit ATR code, including historical bytes to indicate the memory density within theCryptoMemory family. Once the asynchronous mode has been selected, it is not possible to switch to the synchronous mode without powering off the device.Figure 9-1. Asynchronous T = 0 Protocol (Gemplus Patent)V cc I/O-SDARSTCLK-SCL9.2 Synchronous 2-wire Serial InterfaceThe synchronous mode is the default after powering up V CC due to an internal pull-up on RST. For embedded applications using CryptoMemory in standard plastic packages, this is the only communication protocol.• Power-up V CC , RST goes high also• After stable V CC , CLK-SCL and I/O-SDA may be drivenFigure 9-2. Synchronous 2-wire ProtocolNote:Five clock pulses must be sent before the first command is issued10. Communication Security ModesCommunications between the device and host operate in three basic modes. Standard mode is the default mode for the device after power-up. Authentication mode is activated by a successful authentication sequence. Encryption mode is activated by a successful encryption activation following a successful authentication. Table 10-1. Communication Security Modes (1)Note:1. Configuration data include viewable areas of the configuration zone except the passwords:• MDC: Modification Detection Code •MAC: Message Authentication CodeV cc I/O-SDARST CLK-SCL1234511. Security Options11.1 Anti-tearingIn the event of a power loss during a write cycle, the integrity of the device’s stored data may be recovered. This function is optional: the host may choose to activate the anti-tearing function, depending on application requirements. When anti-tearing is active, write commands take longer to execute, since more write cycles are required to complete them, and data are limited to eight bytes.Data are written first to a buffer zone in EEPROM instead of the intended destination address, but with the same accessconditions. The data are then written in the required location. If this second write cycle is interrupted due to a power loss, the device will automatically recover the data from the system buffer zone at the next power-up.In 2-wire mode, the host is required to perform ACK polling for up to 8mS after write commands when anti-tearing is active. At power-up, the host is required to perform ACK polling, in some cases for up to 2mS, in the event that the device needs to carry out the data recovery process.11.2 Write LockIf a user zone is configured in the write lock mode, the lowest address byte of an 8-byte page constitutes a write access byte for the bytes of that page.Example: The write lock byte at $080 controls the bytes from $080 to $087The write lock byte may also be locked by writing its least significant (rightmost) bit to “0”. Moreover, when write lock mode is activated, the write lock byte can only be programmed — that is, bits written to “0” cannot return to “1”.In the write lock configuration, only one byte can be written at a time. Even if several bytes are received, only the first byte will be taken into account by the device.12. Password VerificationPasswords may be used to protect read and/or write access of any user zone. When a valid password is presented, it ismemorized and active until power is turned off, unless a new password is presented or RST becomes active. There are eight password sets that may be used to protect any user zone. Only one password is active at a time, but write passwords give read access also..12.1 Authentication ProtocolThe access to a user zone may be protected by an authentication protocol. Any one of four keys may be selected to use with a user zone.The authentication success is memorized and active as long as the chip is powered, unless a new authentication is initialized or RST becomes active. If the new authentication request is not validated, the card loses its previous authentication and itshould be presented again. Only the last request is memorized.Note: Password and authentication may be presented at any time and in any order. If the trials limit has been reached (after four consecutive incorrect attempts), the password verification or authentication process will not be takeninto accountFigure 12-1. Password and Authentication OperationsREAD ACCESS12.2 ChecksumThe AT88SC0808C implements a data validity check function in the form of a checksum, which may function in standard,authentication or encryption modes.In the standard mode, the checksum is implemented as a Modification Detection Code (MDC), in which the host may read an MDC from the device in order to verify that the data sent was received correctly.In the authentication and encryption modes, the checksum becomes more powerful since it provides a bidirectional dataintegrity check and data origin authentication capability in the form of a Message Authentication Code (MAC). Only thehost/device that carried out a valid authentication is capable of computing a valid MAC. While operating in the authentication or encryption modes, the use of a MAC is required. For an ingoing command, if the device calculates a MAC different from the MAC transmitted by the host, not only is the command abandoned but the mode is also reset. A new authentication and/or encryption activation will be required to reactivate the MAC.12.3 EncryptionThe data exchanged between the device and the host during read, write and verify password commands may be encrypted to ensure data confidentiality.The issuer may choose to require encryption for a user zone by settings made in the configuration memory. Any one of four keys may be selected for use with a user zone. In this case, activation of the encryption mode is required in order to read/write data in the zone and only encrypted data will be transmitted. Even if not required, the host may elect to activate encryption provided the proper keys are known.12.4 Supervisor ModeEnabling this feature allows the holder of one specific password to gain full access to all eight password sets, including the ability to change passwords.12.5 Modify ForbiddenNo write access is allowed in a user zone protected with this feature at any time. The user zone must be written during device personalization prior to blowing the security fuses.12.6 Program OnlyFor a user zone protected by this feature, data within the zone may be changed from a “1” to a “0”, but never from a “0” to a “1”.13. Initial Device ProgrammingTo enable the security features of CryptoMemory, the device must first be personalized to set up several registers and load in the appropriate passwords and keys. This is accomplished through programming the configuration memory of CryptoMemory using simple write and read commands. To gain access to the configuration memory, the secure code must first besuccessfully presented. For the AT88SC0808C device, the secure code is $22 E8 3F. After writing and verifying data in the configuration memory, the security fuses must be blown to lock this information in the device.

All FPGA devices can control the entire configuration process and retrieve data from the configuration EEPROM without requiring an external controller.The configuration EEPROM’s RESET/OE and nCS pins control the tri-state buffer on the DATA output pin and enable the address counter and the oscillator. When RESET/OE is driven Low, the configuration EEPROM resets its address counter and tri-states its DATA pin. The nCS pin also controls the output of the AT17LVxxxA configurator. If nCS is held High after the RESET/OE pulse, the counter is disabled and the DATA output pin is tri-stated. When nCS is driven subsequently Low, the counter and the DATA output pin are enabled. When RESET/OE is driven Low again, the address counter is reset and the DATA output pin is tri-stated, regardless of the state of the nCS.When the configurator has driven out all of its data and nCASC is driven Low, the device tri-states the DATA pin to avoid contention with other configurators. Upon power-up, the address counter is automatically reset.This is the default setting for the device. Since almost all FPGAs use RESET Low and OE High, this document will describe RESET/OE.4.FPGA Master Serial Mode SummaryThe I/O and logic functions of any SRAM-based FPGA are established by a configuration program. Theprogram is loaded either automatically upon power-up, or on command, depending on the state of the FPGA mode pins. In Master mode, the FPGA automatically loads the configuration program from an external memory. The AT17LVxxxA Serial Configuration EEPROM has been designed for compatibility with the Master Serial mode.This document discusses the Altera FLEX FPGA device interfaces.5.Control of ConfigurationMost connections between the FPGA device and the AT17LVxxxA Serial EEPROM are simple and self-explanatory.●The DATA output of the AT17LVxxxA configurator drives DIN of the FPGA devices.●The master FPGA DCLK output or external clock source drives the DCLK input of the AT17LVxxxA configurator.●The nCASC output of any AT17LVxxxA configurator drives the nCS input of the next configurator in a cascaded chain of EEPROMs.●SER_EN must be connected to V CC (except during ISP).AT17LV65A/128A/256A/512A/002A [DATASHEET]Atmel-2322I-FPGA-AT17LV65A-128A-256A-512A-002A-Datasheet_10201466.Cascading Serial Configuration EEPROMsFor multiple FPGAs configured as a daisy-chain, or for FPGAs requiring larger configuration memories, cascaded configurators provide additional memory.After the last bit from the first configurator is read, the next clock signal to the configurator asserts its nCASC output low and disables its DATA line driver. The second configurator recognizes the low level on its nCS input and enables its DATA output.After configuration is complete, the address counters of all cascaded configurators are reset if the RESET/OE on each configurator is driven to a Low level.If the address counters are not to be reset upon completion, then the RESET/OE input can be tied to a High level.The AT17LV65A (NRND) does not have the nCASC feature to perform cascaded configurations.7.AT17LVxxxA Reset PolarityThe AT17LVxxxA configurator allows the user to program the polarity of the RESET/OE pin as either RESET/OE or RESET/OE. This feature is supported by industry-standard programmer algorithms.8.Programming ModeThe programming mode is entered by bringing SER_EN Low. In this mode the chip can be programmed by the 2-wire serial bus. The programming is done at V CC supply only. Programming super voltages are generated inside the chip.9.Standby ModeThe AT17LVxxxA enters a low-power standby mode whenever nCS is asserted High. In this mode,the configurator consumes less than 150μA of current at 3.3V. The output remains in a high-impedance state regardless of the state of the RESET/OE input.7AT17LV65A/128A/256A/512A/002A [DATASHEET]Atmel-2322I-FPGA-AT17LV65A-128A-256A-512A-002A-Datasheet_10201410.Electrical Specifications10.1Absolute Maximum Ratings*10.2Operating ConditionsTable 10-1.Operating Conditions10.3DC CharacteristicsTable 10-2.DC Characteristics for V CC = 3.3V ± 10%Note:1.The AT17LV65A, AT17LV128A, and AT17LV256A are not recommended for new designs.Operating Temperature . . . . . . . . . . . .-40︒C to +85︒C Storage Temperature. . . . . . . . . . . . .-65︒C to +150︒C Voltage on Any Pinwith Respect to Ground . . . . . . . . .-0.1V to V CC +0.5V Supply Voltage (V CC ) . . . . . . . . . . . . . . -0.5V to +7.0V Maximum Soldering Temp.

Atmel 8580B TPM 电源解译应用指南说明书
Atmel-8580B-TPM-Power-Supply-Decoupling-ApplicationNote_042014APPLICATION NOTE Atmel TPM Power Supply Decoupling GuideAT97SC32041 OverviewThe following guidelines are consistent with industry-standard decoupling recommendations for all active system components. Effective decoupling of the power supply inputs to the Atmel ® Trusted Platform Module (TPM) is critical to assuring reliable component performance in a high-density printed circuit board environment. The TPM is a complex system-on-a-chip integrated circuit design containing an internal microprocessor, EEPROM, ROM, and SRAM memories, digital logic, and analog components. The TPM executes firmware operationsindependently of the external system, as well as, executing command operations received over thecommunications bus. As a result, the TPM is subjected to a wide range of frequencies. These signals must be decoupled from the TPM power supply pins to assure consistently reliable operation over the lifetime of the system.Table 1. TPM Power Supply Pins2Atmel TPM Decoupling Recommendations 2.1 Decouple the V CC PinsEffective decoupling of the V CC inputs to the Atmel TPM is critical to assure consistently reliable operation over the lifetime of the system. The Atmel recommendation for a decoupling bypass capacitor within the range of 2200pF to 4700pF is to be placed as close as possible, < 5mm, to each of the V CC pins, located between each V CC pin and the immediately adjacent GND pin. A 0.1μF decoupling bypass capacitor should be placed at the node in which these V CC traces join, which should be as close as possible, < 10mm, to the TPM. In all cases, this bypass capacitor should be closer than the next closest component. All capacitors should be of high quality, with dielectric ratings of X5R or X7R. A low-power state is automatically entered when the chip is idle. No further action is required by the system to enter low-power mode.No other component should be placed closer to the TPM V CC pin than the low frequency decoupling capacitor. Each component should be properly decoupled from the power supply signal to prevent injection of noise onto the power plane. All capacitors should have a high quality dielectric rating of X5R or X7R, depending on the system temperature requirements.2.2 Decouple the SBV3 PinIn order to decouple the SB3V pin, it is recommended that a decoupling capacitor, no smaller than 2200pF and no larger than 4700pF, be placed as near as possible to the SB3V pin, located between the SB3V pin and the immediately adjacent GND pin in order to address high frequency noise. The placement should be less than 5mm from the SB3V pin; although, best performance is achieved when the capacitor is placed directly next to the chip leads. Chip capacitors of size 0402 will fit well between board traces for the 28-pin TSSOP.A second 0.1µF decoupling bypass capacitor should be placed between the SB3V pin and the Supply rail, whichshould be as close as possible (< 10mm) to the TPM. This capacitor will address lower frequency supply noise.No other component should be placed closer to the TPM SB3V pin than the low frequency decouplingcapacitor. Each component should be properly decoupled from the power supply signal to preventinjection of noise onto the power plane. Both capacitors should have a high quality dielectric rating ofX5R or X7R, depending on the system temperature requirements.2.3 Decoupling DiagramsThe below figures illustrate power and ground pins only.Figure 2-1. 28-pin TSSOP3TPM Power Supply Decoupling Guide [APPLICATION NOTE]2Atmel-8580B-TPM-Power-Supply-Decoupling-ApplicationNote_042014。
